Sunresin Seplite® methanol purification series resins are macroporous strong-acid cation exchange resins developed specifically for methanol purification applications.

Sunresin provides advanced ion exchange resin and catalyst resin technologies for THF-related industrial processes, supporting cleaner production, process optimization, and high-value chemical purification.

Sunresin provides integrated resin catalyst and deacidification solutions for catalytic etherification processes. Through its advanced etherification resin catalysts and methanol recovery deacidification resins

Sunresin’s Seplite® LSC740 series is a specialty macroporous resin designed specifically for mercury removal in industrial wastewater. Its unique polymer structure and functional groups provide exceptionally strong affinity for mercury ions across a wide range of water chemistries.

Hydrogen peroxide (H₂O₂) plays a crucial role as an oxidizing agent in caprolactam production — a key raw material for synthetic fibers and engineering plastics such as nylon and polyester.

With the industry's increasing focus on efficiency, stability, and sustainability, Sunresin’s Continuous Ion Exchange system is the choice for forward-thinking producers in the 1,4-butanediol market.

The quality of brine in chlor-alkali production is crucial. Traditional primary brine purification does not meet the required standards, so secondary purification of the brine is necessary.

In concentrated hydrochloric acid, metal ions mainly exist in the form of complex anions. LSC series ion exchange resins can effectively remove iron ions and also remove other metal ions to varying degrees. Contaminated hydrochloric acid passes through a special ion exchange resin, and the exchange process capture the iron thanks to the very high selectivity. Once the LSC series ion exchange resin is saturated with iron ions, it can be regenerated with deionized water (distilled water). After regeneration, the ion exchange resin is restored to its original state and can be repeatedly used for exchange and regeneration.
